I was sightseeing around Grants NM and El Morro. Stopped at museum, which was closed, to have a picnic lunch. Anyway the guy living nearby spotted me and offered to open-up. The museum is modest however work does go into maintaining it and I heard fascinating stories about the region. It was a lovely visit and free of charge. Suspect you should not rely on it being open at any time, either phone or turn up if passing and just look around outside if no one opens it
